Abstract: A key retaining cylinder for a lock operative on standard keys is disclosed. The cylinder of the lock includes an idler ring driven in rotation, with lost motion, by the lock plug. The idler ring is cooperatively disposed with respect to one of the pins so as to restrict the motion thereof when that lock has been used to lock the lock set and to not restrict the movement thereof when that lock has been used to unlock the lock set. Restricted movement of the pin together with the contrapment of the pin within the combinational notch of the key prevents removal of the key. Further features and embodiments are disclosed including provisions for symmetrical operation thereof for left-handed and right-handed doors.
Abstract: A threaded cap for sealing an automotive vehicle fuel tank is provided with a unitary molded central plastic core and a bonnet rotatably mounted on the plastic core. A pair of concentric races are defined on the plastic core. The inner race carries a unitary molded plastic frame which has a pair of resilient, closely spaced transverse cantilevered arms defining a gap therebetween. The frame is also provided with a resilient catch. A unitary molded plastic bolt is reciprocally movable along the gap to engage and disengage the core for rotation with the bonnet. The bolt has two detents which coact with the catch on the frame to hold the bolt at selected unlocking and locking dispositions of movement. The bolt includes a stud which projects into the gap between the arms so that the arms spring bias the bolt toward the locking disposition. A lock mechanism is used to shift the bolt to an unlocking disposition so that the fuel cap be disengaged from the fuel tank inlet pipe.

Abstract: A deadbolt lock mechanism of the single cylinder type is disclosed having a latch bolt which is movable between extended and retracted positions by means of a lock cylinder at one side thereof. A thumbturn, together with manually movable coupling control means for controlling the coupling between the thumbturn and latch bolt are located at the other side of the mechanism. In the bolt retracted position, the coupling control means is movable between coupling enabling and disabling positions to condition the coupling for operation of the latch bolt by the thumbturn in the enabling position thereof, and for disabling such latch bolt operation by the thumbturn in the disabling position. Consequently, the latch bolt is operable by the lock cylinder in any position of the thumbturn and coupling control means, whereas the thumbturn is enabled for operation of the latch bolt only when the coupling control means has been moved into enabling position.
Abstract: A lock system has an elongated key provided with a plurality of permanent magnets spaced axially and angularly apart along the key in a predetermined magnet array. A cylinder having no moving parts defines a passage generally complementary to this key and provided with a plurality of magnetic-field detectors at least some of which are arrayed to be in line with the magnets of the key when it is inserted into the passage. An electronic circuit is connected to these detectors and to an electrically operable latch and is programmed to open the latch when those detectors that are in line with the permanent magnets change state in a manner indicating that they are juxtaposed with the respective magnets, but not when one or more detectors out of line with the magnet array are similarly subjected to a magnetic field.
Abstract: A magnetically operable key comprises a cylindrical casing containing a turnable member, a drive member and a latch, which are all co-rotatably mounted in the casing with the drive member axially displaceable between the turnable member and the latch within the casing. The drive member has a groove defined thereon which has two circumferential portions and a slanted portion interconnecting the circumferential portions. An engagement pin is connected to the casing and extends into the guide groove for causing axial movement of the drive member when the drive member is rotated and when the pin is disposed in the slanted portion. At least one magnetic piece is pivotally mounted to the turnable member and movable by a magnetic key from a misaligned position to an aligned position. The drive member has a cavity for receiving the magnetic piece when aligned to permit axial movement of the drive member. The misaligned magnetic piece abuts against the drive member and prevents axial movement thereof.
Abstract: The invention relates to anti-theft devices for automobile vehicles in which such devices are fixed on the steering column of the vehicle and the aim of the invention is to provide anti-theft steering device which can be adapted to steering column of differing diameters while retaining the necessary security of the fixing. The device comprises a casing containing a locking bolt operated by a security lock and a base to which the casing is secured by means of screws with breakaway heads. The base has a half bore corresponding to the steering column to be equipped with the device and is secured by a flexible member whose first end is selectively fixed by a pin at one of several discrete locations and whose other end is secured to the base in an adjustable manner.
Abstract: The invention relates to an anti-theft device especially but not solely for automobile vehicles which causes blocking of the gear-change lever.The gear-change lever is articulated about an axis substantially parallel with the floor of the vehicle and close to this floor.
